Flow in Disordered Media

In this chapter, we introduce the basic concepts of disordered media. We introduce properties of flow of current or fluids, and then address flow in a percolating system close to \(p:c\) . We will study the behavior numerically, develop a scaling theory, and find properties using the renormalization group approach. Our initial studies will be on the binary porous medium of the percolation system. However, we can also extend our results to more general random media, and we demonstrate how this can be done towards the end of the chapter.
